It appears, that after reports surfaced yesterday that the Red Sox may have heightened their interest in Roy Halladay, Yankees GM Brian Cashman made the proverbial "just checking in" phone call to Blue Jays GM J.P. Ricciardi. As Rosenthal puts it "where the Red Sox go, the Yankees follow, and vice versa."
However, as of now the Yankees are looking more like interested spectators than actual players, but as we all know that could change in a hurry.
Up to this point it's believed that in order for the Yankees to obtain Halladay they would have to part with both Joba Chamberlain and Phil Hughes, as a condition of Ricciardi's AL East "premium" package. But the Yankees have balked at the idea of including both young pitchers, however, Rosenthal does note that it's not out of the realm of possibility for the Yankees to be willing to part with one.
Furthermore, Rosenthal adds that Halladay isn't the only Blue Jay that the Yankees have their sights set on. It looks as though the Yankees have also inquired about Jays' reliever Jason Frasor.
The Yankee bullpen has certainly become much deeper with the recent success of Hughes, but with the Yankees one serious injury away from a "rotation crisis," the idea of adding another reliever seems smart. It would provide the team additional security should they need to move Hughes back to the bullpen.
